Question

Which type of energy increases when an object’s atoms move faster? A.nuclear B.mechanical C.chemical D.thermal

Answer 1

When an object's atoms move faster, its thermal energy increases and the object becomes warmer.

Answer 2

Answer: The correct option is D.

Explanation:

Thermal energy is the internal energy of the object due to the motion of the particles.

The kinetic energy is due to the motion of the particles. If the system has kinetic energy then it will have thermal energy.

When the object's atoms move faster then the thermal energy  increases.

Therefore, the correct answer is thermal energy.
